It's an excellent resource to read analysis of the status of California's at-risk birds using the latest data to describe current populations, ranges, and threats.
Species highlighted in this 450-page book include seabirds, raptors, shorebirds, waterfowl, and perching birds, all of which are represented on a Bird Species of Special Concern list.
This list also notes California habitats with high numbers of special concern bird species, including wetlands, scrublands, grasslands, and riparian forests.
